7 A pp1ication fi1ed February 9, 1921,: Serial No. 443,560. r

and particularlyto a ichair of this type which may be quickly and easily folded to enable the same to be conveniently. carried. V V v V i The structural.v details of a chair constructed in accordance withmy invention are such as to provide a rigid 'an'd'durable,

piece of furniture when; the chair is in its operative position and'one wherein the sta-' bility of the structure is not affected by its propensity to be folded.

The particular details of the inventlon will be more fullydescripted and illus trated in the accompanying specification and drawings in which:

Fig. 1 is a perspective view of a chair constructed in accordance with. my invention,

Fig. 2 is a vertical section of the same partly folded, and V Fig. 3 is a similar View in its folded compact position. 7

Referring now more particularly to the drawings wherein numeral 10 indicates the.

back of the chair having formed rigidly therewith two side members 11 which pro ject downwardly below'the back and form the rear legs 12 of the chair.

A pair of front legs 13 are rigidly connected together by a cross-piece 14, connection being made between the legs 13 and the cross-piece 14 by suitable bolts 15.

From the structure thus far described it will be seen that the rear pair of legs and a front pair of legs are independent of each other but when the device is in its operativeposition, are so arranged as to properly support the seat of the chair.

The bottom or seat of the chair is numbered 16 and may be apertured as indicated,

forsupporti'ng the rear edge of. the seat when thesame is inits operativeposition. A second cross-p1'ece19" is disposed ,lmmediately above; the cross-piece 19 a ,suilicient distancetofpermit the rear edge of the seat Specification of Letters Patent. TTPat nted- Apr-. 11, 1922.

to lie therebetweenp A vertically disposed bolt 2O'passes through both erosspieces and is provided with; a winged thumb nut 21 which bears against the lower side ofcrosspiece 19; The rear of the seat 16 is reduced as indicatedat 16 to enable it to project ticularly Fig. '1); The rear edge of the seat is also suitably slotted as at 22 to acbetween the-posts 11 of the back (see parthe rear edge of the seat to hold the same in place.

The arms 24- of the chair are connected at their forward ends by hinges 25 to the upper ends of legs 13. The rear ends of the arms 24 are pivoted as at 26 to the vertical posts 11 of the back. If the chair is to be used for children a strap 27 may be permanently attached to one of the arms as at 28, with its free end adapted to be inserted in a slot inthe other arm, and retained across the front of the chair by a hook 29.

In folding the chair to'its compact position to enable the same to be conveniently transported, the front pair of legs 13 carrying with it the seat 16 is raised the pivots 26 01 the arms, being the center about which the front pair of legs swing. This movement of the front part of the seat withdraws the rear edge of the seat from its support between the cross-pieces 19 and 19, thereby allowing the same to assume the position illustrated in Fig. 2.

Upon further movement of the front pair I of legs and arms 24 withrespect to the back 10 in the direction of the arrow y (see Fig. 2).the seat 16 will be folded to lie'flush with the front pair of legs and between f the same and the whole structure folded to the position illustrated in Fig. 3; Inas much as the arms 24 are pivoted on. the

outer sides of the posts 11, these arms whenthe chair is folded, willlie flush with the back of the chair.

When the chair is in its operative position the rigidity of the structure is maintained by reason of the seat 16 which at its forward end is positively: connected to the legs 13 through the cross-piece 1 and hinges 25, the rear edge of the seat abutting the posts 11 of the back and being secured thereto by the thumb nut 21.

While the preferred embodiment of my invention is illustrated, it will be apparent that various modifications may be resorted to without departing from the spirit "and scope thereof and I particularly reserve this right. V

Having thus described my invention, What I claim is:

1. A folding chair comprising a back, pair of legs rigidly secured thereto, a pair of front legs rigidly secured together, a seat, means hingedly securing said seat to the pair of front legs, a pair of arms pivot-- ally secured at their rear ends to the back and hingedly secured to the front pair of legs and means for removably supporting the rear edge of said seat upon the back,

comprising a pair of spaced cross-pieces carried by the back, the rear edge of said seat being adapted to be inserted therebetween and a bolt passing through said crosspieces for causing them to engage said seat.

2. A folding chair comprising a back, a pair of legs rigidly connected to said back, a pair of front legs, a cross-piece secured to said front legs, a seat hingedly secured to said cross-pieceto swing forwardly and downwardly against the front pair of legs. a pair of arms hingedly secured to the front pair of legs, said pair of arms being pivotall'y mounted on the back to swing rearwardly and upwardly against the same, said pair of front legs swinging rearwardly and upwardly against said arms and means for removably securing the rear edge of said seat upon the back, comprising two spaced cross-pieces disposed transversely of said back, a bolt passing through said crosspieces, said cross-pieces being adapted to receive the rear edges of said seat therebetween, said seat being slotted to accommodate said bolt, whereby by tightening said bolt said cross-pieces may be bowed to engage said seat.
